The graphite is in the form of a stickor coherent body 'andby means of-apparatus operated by the engine or other apparatus it is subjected to a grinding, cutting or abrading' operation, the resulting. graphite powder being distributed to the contact surfaces of the moving parts. Y

Aniembodiment of the invention that is practical and eifioient is that disclosed in the drawing forming part of this application, in which the invention is shownapplied to a steam or other fluid pressure engine and the graphite in the form of a bar or stick is intermittently subjected to a grinding n or abrading operation brought about by the operation of the engine, the resulting pow-, der being taken up by the fluid medium operating the engine and by it distributed to the moving surfaces in contact.

In the illustrated embodiments of the invention the grinding operation is effected by variation of pressure of the engine operating fluid medium, and by the action of a moving part of the engine. In the drawing: Figure 1 is a view part1 in elevation and section: Fig. 2 is a deta l sectional plan of the construction shown in Fig. 1: Fig. 3, a side elevation showing a reciprocating engine equipped with the invention: Fig. 4 is a detail sectional plan showing a modification: Fig. 5, a sectional elevation showing a further modification: Fig. 6 is a section on the line VI, VI of Fig. 5 and Fig. 7 is a detail section showing another modification. a

An ordinary double acting steam engine cylinder 1 has associated'wit-h it a usual steam chest 2. In a tapped aperture in the top of the steam chest is screwed the tubular threaded reduced end 3 of a hollow body4.

Within this body is rotatably mounted a cutting or grinding wheel 5 upon the periphery of which bears a stick or bar of graphite 6 seated in a vertical tubular extension 7'ofthe body and urged, if desired, against-the wheel by a spring 8 The wheel 5 may turn upon or .with its shaft 9 and has op'eratively associated with it a feed ratchet wheel 10.

.At the end ofa lateral tubular extension 11 of the hollow body is a motor diaphragm l2 confined at its periphery and having applied centrally to its outer face a coiled compression spring 13 whose reaction tends to force the diaphragm inward. Attached centrally to the inner face of the diaphragm is a plunger 14 guided in a bearing 15 'and carrying at its inner end a drive pawlv 16 that engages the ratchet wheel 10. The pawl has applied to it aspring 17 that maintains it in engagement with the ratchet wheel. The confined space at the outer surface of the diaphragm is connected by a pipe 18 with the steam space of the cylinder adjacent one end thereof. When this latter end of the cylinder receives steam, the pressure thereof .supplementing the reaction of spring 13 causes'the diaphragm to move inward and when that end of the cylinder is exhausting and the other end is receivin steam the diaphragm will be forced outwari In this way, during the operation of the engine, there is imparted intermittent rotation to the grinding wheel. The resulting graphite powderis taken up by the steam and by it carried to the various interipr surfaces of the engine such as those of the cylinder and piston, and the controlling valve and its sea It is not intended to confine the invention to a rotary grinder, nor to actuation of the grinder by variation of pressure in the interior spaces of the engine.

drive pawl 16 operated as shown by a moving part 20 of the engine. That is to say, the reciprocating part 20 carries a projection 28 that intermittently strikes the end of an endwise moving rod 24: surrounded by a spring 25 that normally retracts it. The other end of the rod is operatively connected with one end of a rocking lever 26 whose otherend has pivoted in it the drive pawl 16 that engages the ratchet wheel 10, the latter in this construction being located, Fig. 4;, outside the shell In Fig. 7 a reciprocating grinder is shown. It may be in the form of a segment 21 intermittently actuated as shown in Fi 1 through the medium of rod 14 and a lin 22.

In Figs. 5 and 6 the shaft 9 asses out of shell and carries (as in Fig. 4? the driving ratchet wheel 10. Within the shell is a frame 27 that reciprocates at right angles to shaft 9 and is formed with a slot through which the shaft passes. The frame slides back and forth on a dovetail way 28 on the side wall of the shell and carries at,each end a rod 29 that slides in tubular extensions abrading surface 30 is in the form ofan inverted V at the top of the frame. The frame is reciprocated by a cam 31 on shaft 9 working between rollers 32 the frame.

In the various forms 1n which the invention may be embodied the grinding chamber may be connected with one end, or both ends, of the cylinder;

In time invention the graphite supplied to the reservoir or'holder to be acted upon by the cutting, abrading or grinding means is in the form of a solid-that is a mass or body that. retainsits form under all conditions of use when unconfined and has such physical characteristics as that the cutting, abrading or grinding devices act to remove finely divided lubricating particles there-- om.
